STOPPERILIG BOTTLES 'OR OTHER VESSELS.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed May 24, 1907. Serial No. 375,512.

To all whomit mar concern:

Be it known that I, EDWARD ALEXANDER MATTHIAS, a subject of Great Britain, residing at Liverpool, Eriglandyhave invented certain new and useful Improvements in Stoppering Bottles or other Vessels, of which the following is a specification.

This inventionrelates to improvements in that type of stopper for bottles or the like vessels in which inclined surfaces upon the stopper are ada' ted to engage abutments on the neck of the ottle and so press the stop-' per upon a seating in the bottle neck.

I have illustrated my invention in the "accompanying drawings in which Figures 1. and 2..are respectively, aperspece tive view of a stopper showing the inclined planes upon the top surface thereof, and of a bottle neck showing the projections; Fig.7 3. being an analogous view with [the stopper inserted; Fig. 4. is a verticalmedial section through the stopper and bottle neck;.Fig. 5.

isa perspective view of a loose band carrying the inclined, lanes; Fig. 6. being a plan showing thehand in situ on thestopper; Fig. 7. is a section through the stopper and. band of Figs. 5 and 6when the stopper is in place in the bottle. V

When the inclined'planes are integral with the stopper the to surface of the stopper 1 is formed with inc ined planes 2 extending round the upper surface edge of the stopper and abutting against the thumb piece 7 Indents 3 are provided in the edge of the rim of the sto per. When the stopperis inserted in the neo of the bottle 4., these indents pass the projections5 which are formed in the neck of the bottle above the ledge 6. 'Ifthe stopper be now rotated. by the thumb or ridge piece 7 in the direction of the arrow Fig. 1., the stopper will be forced. axially downwards by reason of the wedge action of the inclined planes 2 engaging the projections 5, and the rubber washer 8 will be com: pressed on to the ledge 6, thus making an air tight joint; the full diametral extensionof the thumb piece 7 across the inclined planes 2 serves as a stop tolimit the rotation of the stopper. The stopper is released by rotating it in a contrary direction until the indents 3 are beneath the projections 5, when it may be withdrawn. I

Instead of forming, the inclined planes upon the stopper itself, they may be stamped out of a metal band 9, as indicated in Fig. 5., which is then adaptedto be sprung over the upper flange 10 of the stopper and to be rotatable about this flange. The band is provided With an upstanding ridge or fin 11 for 9 for'the purpose of keeping the band central when belng rotated. There is in this case no relative movement between the stopper and the bottle ledge, but when the stopper is inserted the indents 3 pass the projections 5 and the band 9 is then rotated by means of the ridge or fin 11the stopper remaining stationary until the inclined planes 12 engage the projections 5 inside the bottle neck and the stopper is forced down on its seating, which in this case is the fixed rubber ring 8 resting upon the ledge 6. Any sticking of the stopper against rotation, which frequently arises when there is relative movement between the rubber ring and the fixed ledge, is entirely eliminated.

.What I claim as my invention and desire to secure by Letters Patent is 1. In combination, a bottle neck, projections within said bottle neck, a stopper, circumferential inclined projections on the sto per surface adapted to engage the said bott e neck projections, and a diametral thumb piece joining together the inclined projections and extending across the stopper so as to'form a limiting abutment for the projections, substantially as described.

2. In combination, a bottle neck, projections therein, a stopper provided w1th indents to pass the projections, a cap piece mounted on'the stopper so as to be rotatable relatively thereto, and circumferential in- :clined planes on the cap piece adapted to engage the projections in the bottle neck, substantially as described. a

In witness whereofI have hereunto set my hand in presence of two witnesses.
